Abstract Bond is an essential property that guarantees the composite action in prestressed concrete (PC) members. This bond may be degraded due to different reasons, corrosion‐induced damage being one of the most frequent ones. The transfer length is the key indicator that describes the bond properties between prestressing steel and concrete. The analysis and design of PC members with prestressing wires require a realistic assessment of the bond transfer length. This paper presents an analytical study of the influence of the governing geometrical and mechanical variables on bond behavior in PC members undergoing steel corrosion. A model describing the deterioration of the transfer length due to corrosion, calibrated and verified through experimental tests, is proposed along with simplified expressions for the assessment of transfer lengths in PC members with corroded wires.
